TYPE-WRITING MAQH-INE.

SPECIFICATION forming part of Letters Patent No. 502,147, dated July 25,1893.

Application filed August 13,1892. Serial No. 4%,053- (No model.)

To all whom it may concern.-

Be it known that I, JOHN D. SMITH, a citizen of the United States,residing at Bonham, in the county of Fannin and State of Texas,

5 have invented new and useful Improvements in Type-Writing Machines, ofwhich the following is a specification.

My invention relates to type-Writing machines, and the main objectsthereof are to provide a simple, reliable and easily operated auxiliaryattachment, or apparatus, whereby paper maybe fed to the type in acontinuous web, from which the several sheets, as they are printed, maybe severed in equal lengths,

Without disturbing the engagement of the continuous web with thepaper-cylinder and feeding-devices.

It is my purpose, in other words, to provide a simple and eflicientmechanism capable of being incorporated with, or attached to, atypewriter of any of the known patterns now in use, said mechanism beingso organized that it will feed a continuous web of paper to the type bythe feeding-devices now used upon the different type-writers known tothe public, thereby avoiding the necessity of making any materialchange, either in construction, in the parts constituting thetype-writer, proper, or any addition to, or omission from said parts,which involves any constructive modification of the same.

It is my further purpose to combine with a type-writing machine of anyknown, or preferred form, a simple, eflicient, and comparativelyinexpensive attachment for printing upon a continuous web of paper, andto provide means whereby sheets of any required length may be easily,quickly, and accurately severed from the continuous web, as they areprinted, without disturbing the relations of said web to theteed-mechanism.

It is my purpose, also, to combine with a type-writing machine of anypattern simple means whereby a letter-head may be printed upon eachsheet, of paper, in succession, as it is fed over the paper-cylinder,and before theprocess of printing begins.

It is my further purpose, in this connection, to provide simple meansfor printing a letterhead, or other suitable matter, upon each sheet ofpaper, in succession, as said sheet is fed over the paper-cylinder; theparts being particularly adapted for a type-writingmachine used inprinting upon a continuous web, but capable of use in printingletter-heads upon single, or separate sheets.

It is my purpose, also, to provide means for printing letter-heads, orother suitable matter, upon the paper used in a type-writing machine andto combine with the parts simple devices whereby the mechanism printingthe letter-heads may be rendered operative, or inoperative, ascircumstances may require, and to combine therewith, also, suitableinking-devices, the whole being so organized that it may be operated bythe parts of the typewriter which are operated by the person using thelatter.

Finally, it is my purpose to combine with a type-Writer of any suitableor preferred form, [0 a mechanism for feeding a continuous web of paperto the type, devices for severing sheets of any required lengththerefrom, automatic means for printing a letter-head upon each sheet,and devices for rendering said printing devices inoperative, oroperative, as may be desired, the feed of the continuous Web and theaction of the parts printing the letter-head being produced by themanually operated parts of the type-writer, proper.

The invention consists, in the several novel features of constructionand new combinations of parts hereinafter fully described and then moreparticularly pointed out and delined in the claims terminating thisspecification.

To enable others skilled in the art to make, construct, and use my saidinvention, I will now proceed to describe thesame in detail, referencebeing had to the accompanying 9o drawings, in which- Figure 1, is an endelevation of the top of a Remington type-writer, showing my inven-' tionincorporated therein. Fig. 2, is a plan view of the parts shown inFig. 1. Fig. 3, is 5 a perspective view of the paper-cylinder, theprinting or type-cylinder, the inking-roll and the sheet severingdevice, together with their respective supports. Fig. 4, is a transverseor vertical section taken through the paper and printing-cylinders, theinking-roll and pay-off roll, the point of view being at the left of thetype-writer.

Fig. 7, is a frontelevation showing the paper and printing-cylinders, the paper-guides andthe straight-edge and clamp for the sheet-severing device. Fig. 8, is aplan View of the sheet-severing device and its several adjuncts. Fig. 9,is a longitudinal section of the printing-cylinder. Fig. 10, is an endview of the printing-cylinder showing the automatic disengaging devices.Fig. 11, is a view of the inner face of one of the heads of theprinting-cylinder. Fig. 12, is a detail plan view of one end of theprinting-cylinder.

My invention is applicable to a type-writer of any known or preferredform, and to facilitate and simplify the explanation of the same, I haveshown it, in this instance, as incorporated in, or connected with, aRemington machine, which is as widely and probably as familiarly knownas any pattern of type-writer now in use.

In the said drawings therefor, the reference narrow metallic plate orfiat bar 17, longitudi- 3 nally parallel with the surface of thecylinder, and provided with a plurality of curved numeral 1 indicatesthe top of the Remington machine, with its essential parts, which are ofthe usual well known construction. Said parts comprise the frame, orpaper-carriage, composed of front and rear bars 2 and 3, respectively,and end-bars 4, having the usual mounting upon the type-basket.

In suit-able boxes upon the end-bars 4, are mounted the journals of thepaper-cylinder 5, which is provided at one end with a ratchet 6, withwhich the pawl or dog 7 of the linefeed or carriage-lever 8, makesengagement to give intermittent revolution to the cylinder and therebyadvance the paper by equal feed-movements, as the lines are successivelycompleted.

The remaining constituent parts of the paper-carriage I need notparticularly refer to, asthey are familiarly known to all who areskilled in the art. The parts I have specified above are in the samecategory, but I have made reference thereto because said parts are moreor less intimately connected with the 1 mechanism embodying myinvention.

In applying my invention to the Remington machine, I usually remove thepaper-shelf, which lies in rear of the paper-cylinder 5. While thisremoval may not be absolutely essential for carrying out my purpose, Iprefer to dispense with said paper-shelf, as it is not required where acontinuous web is used, and .its removal avoids any tendency to acumbersome, or top-heavy appearance. Moreover, the removal of thepaper-shelf affords the means of attaching an important part of theweb-supporting mechanism, as I willnow explain more specifically.

Upon the lugs 9, to which the paper-shelf is attached, I mount uprights10, which are usually connected by a metallic plate 12,which liesparallel with the rear bar 3 of the papercarriage. The upper ends ofthese uprights are provided with apertures, or other suitable hearings,in which are placed the journals 13 of a pay-01f roll 14, upon which iswound a continuous web 15 of paper of any suitable or preferred kind orquality. From this payoff roll the paper is led under the paper-cylinder5, around the front face and over the top thereof, its free end beingcarried back over the top of the pay-off roll 14. If the web 15 is takenfrom the rear side of the pay-off roll, the movement of the top of thelatter, as the web is paid off, will be toward the rear, and the paper,which will rest thereon by its own gravity, only, will be constantlycarried to the rear of said pay-off roll as fast as it comes from thetop of the paper-cylinder 5. The web passes between the bottom, or lowerface, of the paper-cylinder 5, and the rubber bands 16, which arecarried by feed-rolls in front and in rear of the paper-cylinder, in themanner usually followed in machines of this construction. The web isprinted in the ordinary way and is fed by the line-space feedlever orcarriage-lever 8.

In front of the paper-cylinder I arrange a paper-guides, orguard-fingers 18, which curve over toward the surface of thepaper-cylinder, their ends closely approaching the same. The function ofthese guides is to direct the end of the web 15, when it is introduced,or

, brought upon the cylinder 5, toward the rear. The bar or strip 17 ispreferably raised somewhat above the uppersurface of the carriage, itsextremities being curved or turned down- 1 ward and then bent toward therear, into substantial parallelism with the end -bars 4. These endsreceive attaching screws 19,which are tapped into the cylinder-shiftslide-bars 4, just in rear of the slots which receive the cylindershift-guides on the end-bars 4.. A second guide-supporting bar 20 isarranged a little below and parallel with the bar, or strip 17, and uponthis second bar are formed, or mounted, curved guide-fingers 21, whichextend downward and rearward in such position as to receive the end-edgeof the web, as the latter is brought upon the cylinder 5, and direct itbetween the guidefingers 18 and the face of the cylinder 5. The secondguide-supporting bar 20 is supported upon the cylinder-shift slide-barst, by arms 22, lying parallel with and inside the said rails. These armsextend rearwardly far enough to catch a bearing upon the shaft of thepaper-cylinder. Near the front rail 2 the ends are bent upwardly, toextend to the upper surface of the said slide-rails, and then bentlaterally, outward, forming horizontal supporting portions 23, restingupon said surface. At one end the engagement is preserved by means of ascrew 24,'which also secures the holding-pawl in place, by which anybacklash of the paper-cylinder is prevented. At the other end of thebar, the supporting-portion 23 rests upon the slide-rail withoutpositive fastening.

. A space is preferably left between the two rails 17 and 20, ofsufficient width to permit the passage of a severing-device, whichpreferably consists of a cutting-roll 26, journaled on a vertical axis27, which is supported upon a forked bracket 28. This bracket isprovided with a clip, or other suitable device, 29, whereby it is soengaged with a rail 30, that it may slide freely thereon from end to endof the paper-cylinder 5, said rail having support upon the upwardlyturned lugs 31, which may be conveniently formed as prolongations of thehorizontal supporting-portions 23. The severing or cutting-roll 26 isformed with a thick bod y-portion having a tread 32, which pressesagainst the outer surface of the guide supporting bar 20, and forces theinner face of said bar closely against the paper web which is therebyclamped, or pinched, between said bar 20 and the surface immediately inrear thereof. The cutting-edge of the roll, which projects beyond thetread 32, rests upon the upper edge 33 of the supporting bar 20, andprojects inside said bar far enough to give its sharp periphery abearing against the paper and press the same against a metal strip 34,lying behind the guide-supporting bar 20 and close to the face of thecylinder. The edge of the said strip 34 rises above the edge 33, of theguide-supporting bar, in order to present an even, metallic surfaceagainst which the cutting-edge of the roll may press the paper, whichpasses between said strip and bar. The ends of the strip are supportedupon the forward extremities of the arms 22, which may be eitherintegral parts of the said strip, or separately formed and suitablyconnected to it. The guide-supporting bar 20 is usually attached tothese arms by bending its ends toward the front and soldering, riveting,or otherwise securing them to the inner faces of the said arms. By thisconstruction the edge 33 of the guide-supporting bar 20 forms astraight-edge for the accurate guidance of the cutting-roll, while thebar itself, in conjunction with the strip 34, serves as a temporaryclamp for the paper, to prevent its slip, or movement, during the actionof the cutting-roll, the clamping-pressure being produced by thepressure of the tread 32 of the cutting-roll.

Upon the cylinder-shift slide-bars 4 are rigidly affixed uprightbrackets 35, having outwardly turned foot-pieces 36, through one ofwhich passes an attaching screw 36, while the other foot-piece restsupon the end of the guidesupporting bar 17 and is fastened by the screw19 above mentioned. Upon these upright brackets are formed, or mounted,lugs 37, in which are formed angular openings, within which are mountedjournal-boxes 38, having heads 39, upon which are angular bosses 40fitting the openings in the lugs 37. The journal-boxes 38 are threadedupon their exterior to enter nuts 41, which lie between the lugs 37 andshoulders 42, at the inner ends of journals 43, which lie in the boxes38. The journals form the supports for the shaft of a roll 44, of anysuitable diameter, and constructed of wood, metal, or other material.Upon the surface of said roll is formed, or attached, a form of type,arranged in accordance with the taste of the user, and containing thematter usually provided for a letterhead, bill-head, or other similarprint, or impression, which will ordinarily include the name of thecity, or town, with a depression or socket in the roll for receivingtype to des ignate year, month and day.

A cheap and convenient method of providing the type is to cast the wholeform in rubber upon a suitable foundation, or plate 45, which may beaffixed to the face of the roll by cement, tacks, or other suitablemeans. This construction is not only inexpensive, but will permit theuse of inter-changeable forms, should circumstances render the samedesirable. It should be noted, however, that a roll having the typeformed thereon, or in any manner attached thereto, is, in all respects,within the scope of my invention. The roll 44 is normally loose upon theshaft, so thatthe latter may turn without obstruction, without impartingmotion to the roll. Upon one end of the shaft of said roll'is rigidlymounted a head 46, having a spur-gear 47, which engages with a spur-gear48 upon the shaft of the paper-cylinder 5. At the other end of theroll-shaft is a head 49, also rigid with the shaft. That side of thishead lying next the end of the roll is provided with an open, circularchannel 50, exposing a series of internal ratchet-teeth 51, formed inthe inner face of the periphery of the head 49. Projecting from the endof the roll is a dog 52, which lies in a recess parallel with the axis,or nearly so, and carrying a point 53, so formed as to engage the saidratchet-teeth 51, when the dog is moved outward, and to be withdrawntherefrom when it is moved acorresponding distance inward. The outwardmovement is effected by means of a spring 54, and the disengagement ofthe dog from the ratchet-teeth is made by a spring-pressed riding-roll55, which travels upon the end of the roll 44 and, at the proper point,rolls upon the outer face of the dog. The riding-roll 55 is journaled inthe forked end of a lever 56, which is operated by a spring of greaterelastic tension than that which throws the dog outward. The dog isdriven inward thereby and disengaged from the ratchet 51. The inwardmovement of the riding-roll is provided for by the formation of a recess57 in the face of the roll, which is arrested the moment disengagementis made. When the roll 44 is made of wood, rubber, or composition, orany material besides metal, I'usually mount a metallic disk 58 on theend thereof and form a shallow slot 59 in the edge thereof to receiveand permit the movement of the point, or end, of the dog 52.

The lever 56 carrying the riding-roll 55 is provided with a rigid sleeve60, which is loosely mounted on the end of a shaft 61, which hasjournal-support in arms 62 forming part of the brackets 35. Upon thesleeve is coiled a spring 63 rigidly attached at one end to thebracket-arm 62, and having its other end extended somewhat from the axisof the sleeve and hooked under the edge of the lever between its fulcrumand the end to which the power is applied.

Upon the shaft 61 is loosely mounted a roll 64 which supplies ink to thetype upon the roll 44, and is, for this purpose, of any suitablematerial and construction. This inking-roll, as well as theprinting-roll 44., is usually covered, or inclosed, by a light shield65, to prevent soiling the paper and the fingers of the operator. Thepower-end of the lever 56 is extended toward the front and is broughtinto such proximity to the corresponding end of the pawl-carrying-leverthat both may be operated by one hand.

In the construction of the mechanism I prefer to dispense with the nuts41, surrounding the journals of the roll-shaft, and to make these, orequivalent devices, as parts of the lugs 37, or other supports, whichreceive the journal-boxes 38. It should be noted, also, that theconstruction may be varied in other respects, without any departure frommy invention, as I do not confine myself to specific details in theconstruction and assemblage of the several parts of the mechanism.

By the organization set forth, I provide a simple apparatus for feedinga continuous web to the type-writing mechanism and for separating, orsevering, sheets therefrom, as printed successively, of any desired ornecessary length. I also provide means for printing letter-heads andbill-heads, or other similar matter, upon each sheet as it is broughtupon the paper-cylinder, said printing devices being, normally, renderedinoperative by antomatic means, and being capable of receiving operativemovement at any moment.

It is an important feature of myinvention that the printing mechanism isactuated wholly by the revolution of the paper-cylinder and dependsprimarily, therefore, upon the pawl-carrying lever, or line-feed leverS, for its action, the paper-cylinder constituting one of theprinting-rolls and corresponding, in that capacity, to theimpression-cylinder of a press using a type-cylinder.

The capacity of utilizing the parts of the type-writer as co-operatingelements in the web-feeding and sheet-severing apparatus, and especiallyin connection with the printing-mechanism, is a feature of the highestimportance, as it enables me to greatly simplify the construction,reduce the number of parts, and very materially diminish the cost ofmanufacture. I am able, also, to benefit by the accuracyof workmanshipand operation which is found in all type-writers which have gained afoothold upon the market.

The use of the invention is compatible, as I have mentioned in apreceding portion of this specification, with any form of type-writingmachine in use, without any material change. I have shown and describedthe same in combination with a Remington machine merely as a matter ofconvenience, and for the further reason that the Remington being amachine which is well known and generally understood, the explanation ofmy in vention in conjunction therewith will require less specificdescription and be readily comprehended.

What I claim is- 1. The combination with the paper-cylinder of atype-writing machine, of a pay-off roll carrying a continuous web ofpaper, a cutting or sheet-severing device traveling on a support infront of the paper-cylinder, and a supporting-strip for the paper behindthe line of out, said strip lying next to and receiving support from thesurface of the pa per-cylinder, under the thrustof the cuttingorsevering-device, substantially as described.
